I concur in part, but only because in order to develop new electronic devices, it is necessary to find innovative solutions to the eco-sustainability problem of materials as substrates for circuits. We realized a photoresponsive device consisting of a semiconducting polymer film deposited onto optically semitransparent and conductive biodegradable poly(3-hydroxybutyrate) (PHB)/carbon nanotube (CNT) substrates. The experiments indicated that the PHB-CNT bionanocomposite substrate behaves as an optical window trapping electric charges produced by the photoexcitation of the semiconducting polymer. Such PHB-CNT functional substrates are expected to be attractive for eco-friendly electronics.

But I have to disagree on your poignant assertation that self-consistent field theory is used to study the directed self-assembly of diblock copolymers under cylindrical confinement; this is particularly relevant in the case of the hole-shrink problem where cylindrical prepatterns are used to produce cylindrical holes with a reduced diameter. Simulations indicate that a variety of regular morphologies form inside the guiding hole, ranging from the highly desired cylindrical domain to disconnected beads and open rings. More complex geometries combining several of the regular morphologies are also observed.
